Definitions
- the process of fabricating the optical fiber is further divided into a process of fabricating an optical fiber preform and a process of drawing an optical fiber from the optical fiber preform.
- the process of fabricating an optical fiber preform is accomplished by utilizing such methods as a modified chemical vapor deposition (MCVD) method, a vapor- phase axial deposition (VAD) method, and an outside vapor deposition (OVD) method.
- MCVD modified chemical vapor deposition
- VAD vapor- phase axial deposition
- OTD outside vapor deposition
- the sintered core layer is doped with a material containing a dopant, especially semiconductor fine particles of nano-size, so that the doping process can be stably executed by means of a conventional apparatus of fabricating an optical fiber perform without an additional apparatus, thereby making it possible to obtain a nonlinear optical fiber having stable characteristics .
- the dopant comprises at least one of PbTe, PbS, SnTe, CuCl, CdS, and CdSe.
- FIGs . 3A to 3D are sectional views for describing the operation of the apparatus shown in FIG. 2;
- a material containing a dopant namely functional solution, is injected from a material supplier 58 into the quartz glass tube 52 with inner annular projections formed by the shrinkage.
- the quartz glass tube 52 when the functional solution containing a dopant is injected into the quartz glass tube 52, the quartz glass tube 52 is rotated so that the dopant permeates the sintered portion of the core layer formed .in the quartz glass tube 52 having a cylindrical shape.
- the dopant may stably remain in the sintered portion even when the core layer has a large sintered portion. Hence, it is possible to increase the quantity of the dopant permeating the core layer .
